Had the Derbi out this weekend and put about 80 mi on it. Took it to a local cycle meet with over 500 cycles in attendance. Plenty of interesting looks and a fair amount of attention.
Ran pretty well. Temps were in the high 40F to low 50F range, and I richened the needle slightly the day before. Lots of fun on the backroads and curves, but struggles with me on it (175#) from a stop. Once it hits 7500 of so it takes off, but not much going on below that...
